Wes, I have weighed quite a few 346s. Most weigh 11.33lbs, but I have seen three or four that were 11lb 7oz. I have not been able to see a difference in the saws, but it is not a scale error. I regularly use my scales to weigh boxes for postage, and my scale is always within .5oz of the PO scales. I also have checked mine against the PB postage meter at work and it is within a couple .1's of an ounce using a 10lb dumb bell. I also know that all saws are "clean" and drained. There might be an ounce of gunk, bar oil, and fuel in the lines, combined, but it is a very close weight.
